Determine the coordinates of the endpoint of a segment CE with one endpoint at C(3,10) and a midpoint at (-1,-6).

Disclaimer: This is 10th grade geometry.

  1. The midpoint is halfway from one end to the other. Just figure out ho wfar you've gone and go twice that far.

    (-1,-6) - (3,10) = (-4,-16)

    That is, you've added (-4,-16) to (3,10) to get to (-1,-6).

    So, add it again:

    (-1,-6) + (-4,-16) = (-5,-22)

  2. Let the endpoint be (x,y)
    so ..
    (x+3)/2 = -1 and (y+10)/2 = -6
    x+3 = -2 and y+10 = -12
    x = -5 and y = -22
    endpoint is (-5,-22)
